In this activity, learners work in teams to construct specific components of a model of the High Energy Solar Spectroscopic Imager (HESSI) spacecraft. Afterwards, the teams make presentations on the results of their effort. Note: HESSI is now named...(View More) the Reuven Ramaty High Energy Solar Spectroscopic Imager, or RHESSI. NOTE: The HESSI mission was renamed RRHESSI (Reuven Ramaty High Energy Solar Spectroscope Imager) after Dr. Reuven Ramaty, who was the original Co-Investigator for this NASA mission, and was a pioneer in the fields of solar physics, gamma-ray astronomy, nuclear astrophysics, and cosmic rays.(View Less)
